The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below: Car A:
y = 52x + 70

Car B:
y = 54x + 56

After how many hours will the two cars be at the same distance from their starting point and what will that distance be?

6 hours, 420 miles
6 hours, 434 miles
7 hours, 420 miles
7 hours, 434 miles

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
